The Oracle VM VirtualBox application installed on the remote host is a version prior to 5.0.22. It is, therefore, affected by multiple vulnerabilities in the bundled OpenSSL component :
A heap buffer overflow condition exists in the EVP_EncodeUpdate() function within file crypto/evp/encode.c that is triggered when handling a large amount of input data. An unauthenticated, remote attacker can exploit this to cause a denial of service condition. (CVE-2016-2105)
A heap buffer overflow condition exists in the EVP_EncryptUpdate() function within file crypto/evp/evp_enc.c that is triggered when handling a large amount of input data after a previous call occurs to the same function with a partial block. An unauthenticated, remote attacker can exploit this to cause a denial of service condition. (CVE-2016-2106)
Flaws exist in the aesni_cbc_hmac_sha1_cipher() function in file crypto/evp/e_aes_cbc_hmac_sha1.c and the aesni_cbc_hmac_sha256_cipher() function in file crypto/evp/e_aes_cbc_hmac_sha256.c that are triggered when the connection uses an AES-CBC cipher and AES-NI is supported by the server. A man-in-the-middle attacker can exploit these to conduct a padding oracle attack, resulting in the ability to decrypt the network traffic.
(CVE-2016-2107)
Multiple unspecified flaws exist in the d2i BIO functions when reading ASN.1 data from a BIO due to invalid encoding causing a large allocation of memory.
An unauthenticated, remote attacker can exploit these to cause a denial of service condition through resource exhaustion. (CVE-2016-2109)
An out-of-bounds read error exists in the X509_NAME_oneline() function within file crypto/x509/x509_obj.c when handling very long ASN1 strings. An unauthenticated, remote attacker can exploit this to disclose the contents of stack memory.
